STAMPING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 730,970, dated June 16, 1903.

Application filed March 13, 1903.

To all whom, it may concern.-

Beit known that I, FRANK I-I. RICKARDS, a citizen of the United States, residing at Centralia in the county of Marion and State of Illinois, have invented a new and useful Stamping-Machine, of which the following is a specification.

The invention relates to certain improvements in stamping-machines, and has for its principal object to provide a mechanism of simple construction adapted especially for the stamping of names or trade-marks on the soles or heels of footwear.

A further object of the invention is to provide a hand-stamp of this character in which the stamping members will have an extensive separating movement for convenience in placing the article to be stamped in position and in which the die member will beuppermost and be held in a stationary position,,so that the operator may readily determine the exact position at which the stamp is to be applied.

A still further object of the invention is to provide a hand-power stamping-machine by which increased leverage may be gained and the effective power gradually increased toward the end of the stamping operation.

With these and other objects in view the invention consists in the novel constructionand arrangement of parts hereinafter described,illustratedin the accom pany'ingdrawings, and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure l is a longitudinal sectional elevation of a stamping-machine constructed in accordance with myinvention. Fig. 2 is a plan view of the same.

The frame of the machine comprises a base 1, from which rise a hollow standard 2 and a curved overhanging arm 3. At the upper end of the arm 3 is a vertical opening 4 for the reception of the shank 5 of a die or stamping member 6, the latter being provided with raised letters or other devices to be stamped in the soles of shoes or in other articles. The shank 5 is vertically adjustable in the open Serial No. 147,639. (No model-l ing 4 and maybe locked in any desired position by means of a set-screw 6, and a number of interchangeable dies may be employed in connection with each machine.

The cooperative stamping member is in the form of a disk 7, which, if the stamped matter is to be embossed, may be provided with either raised or depressed lettering to correspond with that on the upper die 6. The die member 7 is secured to the upper end of a vertically-adjustable stem 8, guided in the hollow standard 2, and the lower end of said stem is recessed, as indicated at 9, for the re-.

i of the hollow standard to form a boss or sleeve 15, having its end terminating at or beyond the edge of the base 1. To the outer end of the shaft 12 is secured one end of a handled operating-lever 16, a locking-key 17 and setscrew 18 being employed to hold the parts rigidly together.

In using the machine the article to be stamped is placed over the die member 7 and the operating-handle is turned to revolve the shaft 12 and raise the stem 8 through the rocker-arm-and-link connection until the article being operated upon is pressed between the two stamping members. As the upper stamping member 6 is stationary, the operator may readily guide the article to proper position, and thus impress the stamp at any desired point.

- It will be observed that the pin-and-rockerits afiorded the stern by the hollow standard 2 will prevent lateral movement of the lower stamping member.

Having thus described the invention, what is claimed is i The combination in a stamping-machine, of the base, a vertically-disposed hollow standard forming a part of the base, a curved arm projecting upwardly from said base and having a vertically-disposed opening at its upper end,an adjustable die member having a shank portion fitting within' said opening, a setscrew for engaging and locking the shank portion in adjusted position, a stamping member -7 of a diameter greater than the opening of the standard and resting on the top of said standard when in inoperative position, a stem 8 guided within the hollow standard and carrying said stamping member, a boss or sleeve projecting laterally from the lower portion of the standard and having an opening forming an extensive supporting-bearing, a rock-shaft 12 fitting Within said bearingopening, an operating-lever secured to the outer end of said rock-shaft, a crank-arm 13 secured to the inner end of said rock-shaft, and a curved link connecting said crank-arm to the lower end of the stem 8, the rock-shaft and stem being so arranged with respect to each other that a portion of the rock-shaft lies in the vertical plane of the stem, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

FRANK H. RICKAR DS.
